Cab driver had his engine running for more than 30min

Thank you for polluting for the past 30min, taxi driver.

Do you know that it is an offence to turn on your engine in carpark (or rather nearby HDB) for more than 5min?

I am staying at 4th floor and I can smell your wonderful exhaust smoke.

Please be considerate to people who are sleeping at night especially those with kids.

NO matter what, you just turn off your engine first. If you want to sleep, please go somewhere further. I will appreciate that.

I have no against to anyone, only irritating person.
